Improving Distribution System Reliability by Means of Distributed Generation
نویسندگان
چکیده
This paper discusses the use of distributed generation (DG) for improving the supply reliability in distribution systems. The first part of the paper contains the results of a simple analytical study of the reliability for individual customers with distributed generation on-site. The difference between disconnector-type interfaces and breaker-type interface is emphasised. In the second part of the paper the reliability improvement for non-DG costumers is studied. General design recommendations are given based on the results.
